CMBPol Mission Concept Study Telecon notes 20 May, 2008 Participants: Bock, Borrill, Cooray, Dodelson, Hanany, Meyer, Ruhl Workshops: Theory workshop: Dodelson reports that the leads of the subgroups are meeting weekly. The workshop will produce a book from the proceedings. The workshop will provide future in parameter uncertainties for different mission sensitivities and angular resolution for the first level study. The second level brings in the issue of band passes and foregrounds. The scanning strategy and focal plane layout are not part of the level 2 study. Systematics workshop: Working on the webpage. So far 15 people have expressed interest in the workshop. Technology Workshop: Working on webpage. New slide showing progress on organization of polarization modulators. All editors for main topics are chosen and work underway to identify leads for sub-topics. All study papers are due June 15 and will be sent out for review. The editors have selected a larger group of people than we had budgeted for. It is likely that we will not be able to fully support the travel of all subtopic leads.
